Predicted to enable identical protein binding activity; snRNA binding activity; and snRNP binding activity. Predicted to be involved in ribonucleoprotein complex localization and spliceosomal tri-snRNP complex assembly. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in Cajal body and nuclear speck. Predicted to be part of nucleus. Is expressed in embryo. Used to study retinitis pigmentosa 11. Human ortholog(s) of this gene implicated in retinitis pigmentosa 11. Orthologous to human PRPF31 (pre-mRNA processing factor 31). [provided by Alliance of Genome Resources, Apr 2022]
